Benefits of technology

【0007】 本発明によれば、低級(炭素数1~3)アルコール含有噴霧水性組成物の噴霧された粒子の収縮を抑制することができる。 これにより、噴射軌道から外れて空間に浮遊する噴霧粒子が少なくなり、目的とする噴霧対象物に、低級(炭素数1~3)アルコール含有噴霧水性組成物を効率的に塗布することが可能となり、非常に有用である。

Claims

1. A method for suppressing the shrinkage of spray particles, characterized in that a spray aqueous composition for fabrics contains 30 to 60% by weight of an alcohol having 1 to 3 carbon atoms and 40 to 60% by weight of water, based on the total amount of the spray aqueous composition for fabrics, and to which hydroxyalkyl chitosan and / or a salt thereof is added.

2. A spray particle shrinkage inhibitor for aqueous spray compositions for fabrics, comprising hydroxyalkyl chitosan and / or a salt thereof as an active ingredient, The aforementioned aqueous spray composition for fabrics is characterized by containing 30 to 60% by weight of an alcohol having 1 to 3 carbon atoms and 40 to 60% by weight of water, based on the total amount of the aqueous spray composition for fabrics, as a spray particle shrinkage inhibitor.
